Azure Communication Services SMS Logs

  • Άρθρο

Azure Communication Services offers logging capabilities that you can use to monitor and debug your Communication Services solution. These capabilities can be configured through the Azure portal.

Important

The following refers to logs enabled through Azure Monitor (see also FAQ). To enable these logs for your Communications Services, see: Enable logging in Diagnostic Settings

Pre-requisites

Azure Communications Services provides monitoring and analytics features via Azure Monitor Logs overview and Azure Monitor Metrics. Each Azure resource requires its own diagnostic setting, which defines the following criteria:

  • Categories of logs and metric data sent to the destinations defined in the setting. The available categories will vary for different resource types.
  • One or more destinations to send the logs. Current destinations include Log Analytics workspace, Event Hubs, and Azure Storage.
  • A single diagnostic setting can define no more than one of each of the destinations. If you want to send data to more than one of a particular destination type (for example, two different Log Analytics workspaces), then create multiple settings. Each resource can have up to five diagnostic settings.

The following are instructions for configuring your Azure Monitor resource to start creating logs and metrics for your Communications Services. For detailed documentation about using Diagnostic Settings across all Azure resources, see: Enable logging in Diagnostic Settings

Note

Under diagnostic setting name please select “SMS Operational” to enable the logs for SMS.

Overview

SMS operational logs are records of events and activities that provide insights into your SMS API requests. They captured details about the performance and functionality of the SMS primitive, including details about the status of message whether they were successfully delivered, blocked, or failed to send. SMS operational logs contain information that help identify trends and patterns, resolve issues that might be impacting performance such failed message deliveries or serve issues. The logs include the following details:

  • Messages sent.
  • Message received.
  • Messages delivered.
  • Messages opt-in & opt-out.

Resource log categories

Communication Services offers the following types of logs that you can enable:

  • Usage logs - provides usage data associated with each billed service offering
  • SMS operational logs - provides basic information related to the SMS service

Usage logs schema

Property Description
Timestamp The timestamp (UTC) of when the log was generated.
Operation Name The operation associated with log record.
Operation Version The api-version associated with the operation, if the operationName was performed using an API. If there's no API that corresponds to this operation, the version represents the version of that operation in case the properties associated with the operation change in the future.
Category The log category of the event. Category is the granularity at which you can enable or disable logs on a particular resource. The properties that appear within the properties blob of an event are the same within a particular log category and resource type.
Correlation ID The ID for correlated events. Can be used to identify correlated events between multiple tables.
Properties Other data applicable to various modes of Communication Services.
Record ID The unique ID for a given usage record.
Usage Type The mode of usage. (for example, Chat, PSTN, NAT, etc.)
Unit Type The type of unit that usage is based off for a given mode of usage. (for example, minutes, megabytes, messages, etc.).
Quantity The number of units used or consumed for this record.

SMS operational logs

Property Description
TimeGenerated The timestamp (UTC) of when the log was generated.
OperationName The operation associated with log record.
CorrelationID The ID for correlated events. Can be used to identify correlated events between multiple tables.
OperationVersion The api-version associated with the operation, if the operationName was performed using an API. If there's no API that corresponds to this operation, the version represents the version of that operation in case the properties associated with the operation change in the future.
Category The log category of the event. Category is the granularity at which you can enable or disable logs on a particular resource. The properties that appear within the properties blob of an event are the same within a particular log category and resource type.
ResultType The status of the operation.
ResultSignature The sub status of the operation. If this operation corresponds to a REST API call, this field is the HTTP status code of the corresponding REST call.
ResultDescription The static text description of this operation.
DurationMs The duration of the operation in milliseconds.
CallerIpAddress The caller IP address, if the operation corresponds to an API call that would come from an entity with a publicly available IP address.
Level The severity level of the event.
URI The URI of the request.
OutgoingMessageLength The number of characters in the outgoing message.
IncomingMessageLength The number of characters in the incoming message.
DeliveryAttempts The number of attempts made to deliver this message.
PhoneNumber The phone number the SMS message is being sent from.
SdkType The SDK type used in the request.
PlatformType The platform type used in the request.
Method The method used in the request.
NumberType The type of number, the SMS message is being sent from. It can be either LongCodeNumber or ShortCodeNumber or DynamicAlphaSenderID
MessageID Represent the unique messageId generated for every outgoing and incoming message. This can be found in the SMS API response object
Country Represent the countries/regions where the SMS messages were sent to or received from
